CT Scans of Tubes – Teslovak KT88S
Just thought I’d plug this cool find from Boing Boing Gadgets – CT scan of a vacuum tube. These were used in the outputs of the Manley 100/100 Amplifier.
The scans are on display on radiologyart.com and were created by artist/med student Satre Stuelke. There’s lots of other things – phones, toys, foood, etc. and they’re all cool looking. But it was the vacuum tube scans tht caught my eye.
If you’re interested, here’s a description from ManleyLabs.com:
The Manley 100 /100 integrated amplifier was our biggest stereo or two-channel model on a single chassis employing a common power transformer but with dual-channel rectification and separate filter / reservoir capacity banks. Retail price was $4400 USD.
Three inputs were provided (TAPE. CD, & TUNER) together with a precision stepped volume-control ensuring absolute channel balance, or sometimes a well-matched Noble® stereo potentiometer. There was a fourth position on the input select switch marked “DIRECT” which bypassed the input switching and volume-control enabling this unit to be used like a normal stereo amp with a separate preamplifier.
A mute switch was also provided, very handy for avoiding noise when swapping interconnect cables or front end electronics so you didn’t have to alter your volume control setting. The chassis parts grew thicker and sturdier after seeing previous incarnations suffer shipping damage occasionally.
In each output stage was a pair of the luscious Teslovak KT88S (pictured above) or the well-proven Russian 6550C’s running in ULTRA-LINEAR (or PARTlAL-TRIODE) mode.
